Ok 1st post so I'll start by saying howdy then I'll start from the begining

I have a '98 GC8 WRX, and after having someone work on it they swapped the overflow hose over with the radiator hose and it ended up overheating and died

I ended up buying a EJ20 turbo off ebay which ended up being out of a '99 forrester.. Have swapped the motors and gone through the hell of hooking it all up (Who would have thought in 1 year they would change so much)

but I am stuck with two different Ignition Coils, Both Diamond, one is a F-569 (which is wired with red, blue and yellow) and the other is a FH0161 (which is wired red, blue, yellow and black) .. I need to use the F-569 as it is smaller and is off the forrester engine, but the wiring I have hooked up is from the wrx I need to know what the black wire is? I'm thinking it's a earth ...

 

And I recently ran around town trying to get an auto electrician to look at it but was told to google it.. Useless

 

Is your original coil center of the manifold? If so it has a seperate ignitor and is not a direct swap with the 99 coil which has a built in ignitor.

 

The Coil from the WRX was on the right side and the Forrester coil was in the centre
